Question

3х/4х+4у-6х/8х+8у решить

Answer 1

Не уверена что так. но больше никак не могу решить

Answer 2

To simplify the given expression, we can first find the lowest common denominator (LCD) of the fractions.

The LCD of 4х+4у and 8х+8у is 8(х+у). We can rewrite each fraction using this denominator:

3х/(4х+4у) = 3х/4(х+у)

-6х/(8х+8у) = -6х/8(х+у) = -3х/4(х+у)

4у/(4х+4у) = у/(х+у)

Putting everything together, we get:

3х/4(х+у) + у/(х+у) - 3х/4(х+у)

= (3х - 3х)/(4(х+у)) + у/(х+у)

= 0 + у/(х+у)

= у/(х+у)

Therefore, the simplified expression is у/(х+у).
